Abstract
Abstract The blade of the stick is formed by placing two blade sections against the lower tapered end of a handle of the stick. The two blade sections are each made as laminated sections, made up of two laminations of wood with a fiberglass layer therebetween. The grain of the two wood pieces of each blade section are offset 45° to one another for greater shear strength. The cavity between the two blade sections is filled with a pliable material that hardens to make the complete blade structure. The outer surfaces of the blade and the side surfaces of the handle are coated with layers of fiberglass.
